Make the present invention in view of the foregoing, and a kind of it is an object of the invention to provide simplification being capable of structure
Isolation mounting with the summary manufacturing.
For solution to problem
In order to solve the above problems, the present invention proposes below scheme.Included according to the isolation mounting of the present invention：Second installation
This two installation component of first installation component of component and tubular, described first installation component and vibration generating unit and vibration acceptance division
Any one of connection, described second installation component with described vibration the other of generating unit and described vibration acceptance division connection
Connect；Elastomer, described elastomer makes this two installation component couple；And partition member, described partition member by described first pacify
The liquid room of the inclosure liquid in dress component is separated into the first liquid room and the second liquid room.In described first liquid room and described second liquid room
At least described first liquid room using described elastomer as a part for wall.It is formed with permission described the in described partition member
The limit path that one liquid room is communicated with each other with described second liquid room.Described limit path includes the first limit path and the second restriction
Path, described first limit path produces resonance with respect to the input of the first vibration, and described second limit path is with respect to amplitude
The input of second vibration bigger than the amplitude of the described first vibration produces resonance.Described first limit path includes pressure loss list
Unit, described pressure loss unit makes the pressure of the liquid in its internal circulation produce loss.Described pressure loss unit is provided with
Medial compartment, the first communication paths and the second communication paths, described medial compartment configures in described partition member, described first connection
Path allow described medial compartment communicate with each other with described first liquid room, described second communication paths permission described medial compartment with described
Second liquid room communicates with each other.The opening of first peristome of the inside opening towards described medial compartment in described first communication paths
The opening axis of the second peristome of the inside opening towards described medial compartment in mouthful axis and described second communication paths that
This staggers.At least one of described first peristome and described second peristome are opened towards the wall limiting described medial compartment
Mouthful.Described pressure loss unit includes first pressure loss unit, in described first pressure loss unit, described first connection
Path is directly connected with described first liquid room and described first peristome is towards the wall opening limiting described medial compartment.Described
In first pressure loss unit, the part towards described first peristome in the wall of the described medial compartment of restriction is by elastica shape
Become.
In this case, if vibration is imported into isolation mounting, the first installation component and the second installation component make
Relative shift while elastomeric resilient deformation.In this case, liquid inclination is in logical between the first liquid room and the second liquid room
Cross the first limit path circulation.
Here, if the first vibration is transfused to, accordingly, time per unit has on a small quantity the amplitude vibrating with first
Liquid inclination in flowing in the first limit path.As a result, the liter of suppression flow velocity of liquid of circulation in the first limit path
High.Therefore, liquid is indoor in the middle of pressure loss unit passes through short path it is suppressed that liquid is in pressure loss unit
The pressure loss, so that liquid gently circulates in the first limit path.Therefore, it is possible to make liquid energetically flow by
Resonance in one limit path, and the first limit path can be used in first vibration that absorbs and decay.
Meanwhile, if the second vibration is transfused to, accordingly, time per unit has in a large number the amplitude vibrating with second
Liquid inclination in flowing in the first limit path.As a result, in the first limit path, the flow velocity of the liquid of circulation can raise.Suitable
Just, in this isolation mounting, in pressure loss unit, at least one of the first peristome or the second peristome are towards limit
Determine the wall opening of medial compartment.Therefore, if raised by the flow velocity that this peristome flows into middle indoor liquid, liquid exists
Directly flow and reach wall in middle interior.Then, liquid flows along wall, reaches to flow in medial compartment with this liquid and is led to
The different peristome of the peristome crossed, and flow out from medial compartment.Therefore, in the case that the second vibration is transfused to, with first
Vibrate situation about being transfused to compare, liquid can circulate in the indoor path along length in centre, and can be in liquid and centre
Friction is produced between the wall of room.As a result, it is possible to produce big energy loss such that it is able to increase the pressure loss of liquid.
This makes liquid be difficult to circulate by the first limit path, thus easily makes liquid pass through the second limit path stream
Logical.In this case, circulate in the second limit path with liquid, resonance can be produced in the second limit path, and
Can absorb and decay the second vibration.
If resonance produce in like fashion in the second limit path, in the first liquid room and the second liquid room with elastomer
Hydraulic pressure as the first liquid room of a part for wall significantly can change along with this resonance.Here, in isolation mounting, the
First communication paths of one pressure loss unit are directly connected with the first liquid room, and in first pressure loss unit, limit
The part towards the first peristome in the wall of medial compartment is formed by elastica.Therefore, if the hydraulic pressure of the first liquid room as above
Significantly change describedly, then the first communication paths in unit and medial compartment can be lost by this hydraulic radial by first pressure
Be delivered to elastica.As a result, elastica being capable of the variation of hydraulic pressure based on the first liquid room and elastic deformation.In this case,
Elastica is lost the first peristome elastic deformation of unit by it towards first pressure and can be closed the first peristome.This energy
Enough make liquid be more difficult to circulate by the first limit path, be thus easier to make liquid pass through the second limit path circulation.Therefore,
For example, even if second vibration with little amplitude is transfused to it is also possible to make liquid reliably flow by the second limit path.
As a result, in addition can reliably absorb and decay have little amplitude second vibration.
As described above, by replace in partition member setting as prior art plunger member and in the first limit path
Middle setting pressure loss unit, can absorb and decay both the first vibration and the second vibration.Therefore, it is possible to realize isolation mounting
The simplification of structure and manufacture summary.
Described pressure loss unit includes second pressure loss unit, in described second pressure loss unit, described the
Two communication paths are directly connected with described second liquid room and described second peristome is towards the wall opening limiting described medial compartment.
The described medial compartment that described first pressure loses unit can clip institute with the described medial compartment of described second pressure loss unit
State elastica ground adjacent one another are.In described second pressure loss unit, limit in the wall of described medial compartment towards described
Partly being formed by described elastica of second peristome.
In this case, first pressure loses the medial compartment of unit and the medial compartment of second pressure loss unit clips elasticity
Film ground is adjacent one another are.Therefore, when the second vibration is transfused to, the liquid being received based on the medial compartment losing unit from first pressure
Pressure and the difference between the hydraulic pressure that the medial compartment that second pressure loses unit receives, elastica loses unit to first pressure
Medial compartment side or the medial compartment side elastic deformation losing unit to second pressure.Here, in isolation mounting, second pressure is lost
Second communication paths of unit are directly connected with the second liquid room, and in second pressure loss unit, limit the wall of medial compartment
The part towards the second peristome in face is formed by elastica.Therefore, when second vibration be transfused to when, can make elastica from
The hydraulic pressure that the medial compartment of second pressure loss unit receives is equal to the hydraulic pressure of the second liquid room.Therefore, when the second vibration is transfused to
When, can increase that elastica loses the hydraulic pressure that receives of medial compartment of unit from first pressure and elastica is lost from second pressure
The hydraulic pressure that the medial compartment of unit receives differ from such that it is able to make elastica to first pressure lose unit medial compartment side or to
Second pressure loses the medial compartment side elastic deformation of unit.If the medial compartment side that elastica loses unit to first pressure becomes
Shape, then elastica can close the first peristome that first pressure loses unit as mentioned above.Meanwhile, if elastica is to second
The medial compartment side of pressure loss unit deforms, then elastica can close the second peristome that second pressure loses unit.
According to more than, even if having little amplitude second vibration be transfused in the case of it is also possible to be held by elastica
Closing first pressure of changing places loses the first peristome of unit or second pressure loses the second peristome of unit.As a result, energy
Enough make liquid be more difficult to circulate by the first limit path, thus enable that liquid circulates more easily by the second limit path.
Any one of described first communication paths and described second communication paths can be to described in described medial compartment
The circumferential openings of medial compartment.In the middle of described with inflow, the flow velocity of indoor liquid accordingly, can be with shape in described middle interior
Become the vortex of liquid.This liquid is from described first communication paths and the outflow of the other of described second communication paths.
In this case, when liquid is circulated by medial compartment, if from the first communication paths and the second communication paths
Any one of flow into medial compartment liquid flow velocity sufficiently high, then can be in the vortex of middle interior formation liquid.Then, liquid
The pressure loss of body can be for example because forming the energy loss that this vortex leads to, because of the friction between liquid and the wall of medial compartment
Energy loss leading to etc. and effectively increase.
Meanwhile, if the flow velocity of liquid is low, liquid can be suppressed in medial compartment inside vortex.Therefore, it is possible to make liquid put down
Pass through medial compartment slowly, and the increase of the pressure loss of liquid can be suppressed.
First pressure loss unit in, limit medial compartment wall in be provided with the first peristome and towards elastica
Partly can be formed towards elastica protrusion convex surface shape.
In this case, in described first pressure loss unit, the setting in the wall of the described medial compartment of restriction is
State the first peristome and the part towards described elastica is formed towards the convex surface shape that described elastica is protruded.Therefore,
When elastica towards the first peristome elastic deformation to close the first peristome when, can make elastica and medial compartment wall it
Between contact area be gradually increased.Thus, for example, the generation of lap (striking sound) can be suppressed.
The effect of invention
In accordance with the invention it is possible to realize the simplification of the structure of isolation mounting and the summary of manufacture.

In isolation mounting 10 as shown in Figures 1 to 4, the first limit path 51 is with respect to idle vibration (for example, frequency
For 18Hz to 30Hz, amplitude is ± below 0.5mm) input produce liquid column resonance.Meanwhile, the second limit path 52 is with respect to trembling
The input of dynamic vibration (for example, frequency is below 14Hz, and amplitude is more than ± 0.5mm) produces liquid column resonance.(second shakes for shake vibration
Dynamic) frequency ratio idle vibration (the first vibration) frequency low.The amplitude of the amplitude ratio idle vibration of shake vibration is big.
It is to make based on such as flow path length, flowing path section area etc. when right that each limit path 51 or 52 is set (adjustment)
The vibration answered is inputted respectively and liquid L produces liquid column resonance in each limit path 51 or 52 internal circulation.For example, as
One limit path 51, can adopt and be constructed as below：In this configuration, first pressure loses second communication paths of unit 53a
The resonant frequency of first communication paths 57 of 58 resonant frequency or second pressure loss unit 53b is set to and idle vibration
Frequency equal.
In the state of vibration is not transfused to, the flow resistance of the first limit path 51 is than the flowing of the second limit path 52
Resistance is little.In isolation mounting 10, after vibration is just transfused to, compared with the second limit path 52, liquid L tends to more long-pending
The first limit path 51 is passed through in polar region flowing.Furthermore it is possible to adjust each restriction lead to based on flow path length, flowing path section area etc.
The flow resistance on road 51 or 52.
Then, by the effect of explanation isolation mounting 10.
That is, if the vibration on axes O direction is input to isolation mounting 10 from vibration generating unit, two installation components make
Elastomer 13 elastic deformation ground relative shift, so that the hydraulic pressure of main liquid chamber 14 changes.Then, liquid L tends in main liquid chamber
Reciprocal between 14 and secondary liquid room 15.In this case, the liquid L in main liquid chamber 14 and secondary liquid room 15 tends to flowing and passes through two limits
The first limit path 51 having compared with small flow resistance in path 51 and 52 processed.
Here, the amplitude of the amplitude ratio shake vibration of idle vibration is little, the velocity ratio when idle vibration is transfused to for the liquid L
The flow velocity when shake vibration is transfused to for the liquid L is little.
That is, if idle vibration is inputted along axes O direction, with the amplitude of this idle vibration accordingly, per unit
Time has a small amount of liquid L and tends to flow in the first limit path 51.Result is it is suppressed that flow in the first limit path 51
The rising of the logical flow velocity of liquid L.Therefore, liquid L passes through short road in the medial compartment 55 of pressure loss unit 53a and 53b
Footpath it is suppressed that the pressure loss in pressure loss unit 53a and 53b for the liquid L so that liquid L is in the first limit path 51
Inside gently circulate.For example, as shown in the double dot dash line of Fig. 5, the second communication paths 58 losing unit 53a from first pressure flow
Enter the liquid L of medial compartment 55, the first communication paths 57 losing unit 53b from second pressure flow into liquid L of medial compartment 55 etc.
Flowing or flowing in the case of a small amount of vortex in the case of not being vortexed in medial compartment 55.Therefore, it is possible to make liquid L put down
Pass through medial compartment 55 slowly, and the increase of the pressure loss of liquid L can be suppressed.Therefore, it is possible to make liquid L energetically flow
By the first limit path 51, and resonance can be produced in the first limit path 51 with the idle vibration that absorbs and decay.
Meanwhile, if shake vibration is inputted along axes O direction, the amplitude vibrating with this shake is accordingly, often single
The position time has substantial amounts of liquid L and tends to flow in the first limit path 51 from main liquid chamber 14.As a result, in the first limit path
In 51, the flow velocity of the liquid L of circulation is increased to the speed of more than particular value.
In isolation mounting 10 as shown in Figures 1 to 4, when the liquid L in main liquid chamber 14 tends to limit by first
Towards when flowing secondary liquid room 15 side, first, liquid L flows in first pressure loss unit 53a path 51 from main liquid chamber 14.At this
In the case of, if raised by the flow velocity that the first communication paths 57 flow into the liquid L in medial compartment 55, from the first peristome
Liquid L in 59 inflow medial compartments 55 directly flows along axes O direction (the first opening axis L1 direction) in medial compartment 55.Knot
Really, reach the part being formed by elastica 39 in the wall of restriction medial compartment 55 in liquid L and stream is changed to along wall
Afterwards, liquid L reaches the second peristome 60 and flows out from medial compartment 55.Therefore, in the case that shake vibration is transfused to, and idle
The situation that speed vibration is transfused to is compared, and liquid L can be made in medial compartment 55 along long path circulation, and can be in liquid
Friction is produced between the wall of L and medial compartment 55.As a result, the pressure loss of liquid L can be because of the viscosity of energy loss, liquid L
Resistance etc. and increase.
Having flowed, it is single to reach second pressure loss by the liquid L that first pressure loses unit 53a by connecting path 54
First 53b.In this case, liquid L is by flowing by the first communication paths 57 by along after above-mentioned tangential direction rectification
Flow in medial compartment 55 from the first peristome 59.Then, liquid L whirlpool in medial compartment 55 as shown in the double dot dash line in Fig. 6
Rotation.That is, if the flow velocity of liquid L raises when the first peristome 59 flows into medial compartment 55 in liquid L, this liquid L is in centre
Directly flow in room 55, reach the inner peripheral surface (wall) of medial compartment 55, and stream is changed to along this inner peripheral surface.
As a result, for example, owing to the viscous drag of liquid L, because formed vortex and lead to energy loss, because liquid L with
Friction between the wall of medial compartment 55 and energy loss of leading to etc., the pressure loss of liquid L can increase.Additionally, in this feelings
Under condition, if the flow flowing into the liquid L in medial compartment 55 significantly raises, medial compartment 55 with the flow velocity rising of liquid L
Interior full of the vortex being become by the liquid L-shaped that has been flowed in medial compartment 55.In this condition, tend to further flow in liquid L
In the case of in medial compartment 55, the pressure loss of liquid L can be increased.Medial compartment 55 inside vortex liquid L from the second opening
Portion 60 flows out, and flows in secondary liquid room 15.
In isolation mounting 10 as shown in Figure 1 and Figure 4, when the liquid L in secondary liquid room 15 tends to limit by first
Towards when flowing main liquid chamber 15 side, first, liquid L flows in second pressure loss unit 53b path 51 from secondary liquid room 15.At this
In the case of, if raised by the flow velocity that the second communication paths 58 flow into the liquid L in medial compartment 55, from the second peristome
Liquid L in 60 inflow medial compartments 55 directly flows along axes O direction (the second opening axis L2 direction) in medial compartment 55.Knot
Really, reach the part being formed by elastica 39 in the wall of restriction medial compartment 55 in liquid L and stream is changed to along wall
After face, liquid L reaches the first peristome 59 and flows out from medial compartment 55.Therefore, it is possible to make liquid L in medial compartment 55 along
Long path circulation, and friction can be produced between the wall of liquid L and medial compartment 55 such that it is able to increase liquid L's
The pressure loss.
Having flowed, it is single to reach first pressure loss by the liquid L that second pressure loses unit 53b by connecting path 54
First 53a.In this case, liquid L is by flowing by the second communication paths 58 by along after above-mentioned tangential direction rectification
Flow in medial compartment 55 from the second peristome 60.Then, liquid L whirlpool in medial compartment 55 as shown in the double dot dash line in Fig. 6
Rotation.That is, if the flow velocity of liquid L raises when the second peristome 60 flows into medial compartment 55 in liquid L, this liquid L is in centre
Directly flow in room 55, reach the inner peripheral surface (wall) of medial compartment 55, and stream is changed to, along this inner peripheral surface, thus increase
The pressure loss of liquid L.Afterwards, liquid L flows in main liquid chamber 14 from the first peristome 59.
As described above, in isolation mounting 10 as shown in Figure 1 and Figure 4, when shake vibration is transfused to, the pressure of liquid L
Power is lost in first pressure loss unit 53a and second pressure loss unit 53b both of which increases.This can make liquid L be difficult to
Circulated by the first limit path 51, so that liquid L is circulated easily by the second limit path 52.In this case, with
Liquid L circulates in the second limit path 52, can produce resonance such that it is able to absorbing and decaying in the second limit path 52
Shake vibration.
Meanwhile, if shake vibration is transfused to and produces resonance, the hydraulic pressure of main liquid chamber 14 in the second limit path 52
Significantly can change with this resonance.Here, in isolation mounting 10, first pressure loses first communication paths 57 of unit 53a
Directly connect with main liquid chamber 14, and in first pressure loss unit 53a, limit in the wall of medial compartment 55 towards first
The part of peristome 59 is formed by elastica 39.Therefore, if the hydraulic pressure of main liquid chamber 14 significantly changes, can press by first
This hydraulic radial is delivered to elastica 39 by the first communication paths 57 in power loss unit 53a and medial compartment 55.As a result, bullet
Property film 39 being capable of the variation of hydraulic pressure based on main liquid chamber 14 and elastic deformation.
In the present embodiment, first pressure loses the medial compartment 55 of unit 53a and second pressure is lost in unit 53b
It is adjacent one another are that compartment 55 clips elastica 39 ground.Therefore, when shake vibration is transfused to, lose unit based on from first pressure
Hydraulic pressure that the medial compartment 55 of 53a receives and between the hydraulic pressure that the medial compartment 55 that second pressure loses unit 53b receives
Difference, elastica 39 loses medial compartment 55 side or the medial compartment 55 to second pressure loss unit 53b of unit 53a to first pressure
Side elastic deformation.Here, in isolation mounting 10, second pressure loses second communication paths 58 of unit 53b and secondary liquid room 15
Directly connect, and in second pressure loss unit 53b, limit in the wall of medial compartment 55 towards the second peristome 60
Part is formed by elastica 39.Therefore, when shake vibration is transfused to, elastica 39 can be made to lose unit from second pressure
The hydraulic pressure that the medial compartment 55 of 53b receives is equal to the hydraulic pressure of secondary liquid room 15.In the present embodiment, because secondary liquid room 15 is by barrier film
Pressure in 17 closings and secondary liquid room 15 is equal to atmospheric pressure, so elastica 39 can be made to lose unit 53b's from second pressure
The hydraulic pressure that medial compartment 55 receives is equal to atmospheric pressure.Therefore, it is possible to increase elastica 39 from first pressure loss unit 53a
The difference of the hydraulic pressure that the medial compartment 55 that the hydraulic pressure that compartment 55 receives loses unit 53b with elastica 39 from second pressure receives,
So as to make elastica 39 lose medial compartment 55 side of unit 53a or to second pressure loss unit 53b's to first pressure
Medial compartment 55 side elastic deformation.
If elastica 39 loses the medial compartment 55 side elastic deformation of unit 53a to first pressure, the first pressure can be made
The first peristome 59 that power loses unit 53a is closed by elastica 39.If elastica 39 loses unit 53b's to second pressure
Medial compartment 55 side elastic deformation, then can make the second peristome 60 that second pressure loses unit 53b be closed by elastica 39.?
In the case of being somebody's turn to do, close first pressure by using elastica 39 and lose the first peristome 59 or second pressure in unit 53a
Second peristome 60 of loss unit 53b, can make liquid L be more difficult to circulate by the first limit path 51.Therefore, it is possible to make
Liquid L circulates easily by the second limit path 52.Even if thus, for example, the shake vibration of the little vibration of amplitude is transfused to,
Liquid L can be made reliably to flow by the second limit path 52.Absorb can and decay have little shake as a result, or even reliably
The shake vibration of width.
Additionally, in the present embodiment, in pressure loss unit 53a and 53b, it is formed towards bullet towards wall 56
Property film 39 protrude convex surface shape.Therefore, when elastica 39 elastic deformation loses first opening of unit 53a to close first pressure
When oral area 59 or second pressure lose second peristome 60 of unit 53b, can make elastica 39 and medial compartment 55 wall it
Between contact area be gradually increased.Thus, for example, the generation of lap can be suppressed.
As described above, according to the isolation mounting 10 of present embodiment, by replacing setting in partition member 16 such as existing
The plunger member of technology and in the first limit path 51 arrange pressure loss unit 53a and 53b, can absorb and damping flicker
